Application October 29; 1937, Serial No. 171,775

2 Claims.

This invention relates to improvements in brushstructures and more particularly to a novel type of handle structure adapted to receive and carry a plurality of brushes.

It is an object of the present invention to provide a new and useful brush handle structure which is characterized in that it is adapted to carry a plurality of brushes, whereby any of the brushes can be substantially freely moved during use of the device but whereby they can be yieldably held in different positions as the operator may desire during use.

It is another object of the present invention to provide a structure of the type indicated which is characterized in that the brushes carried on the handle are freely rotatable about portions thereof, this quality being substantially unaffected by immersion of the' brush in water or the like whereby the portion wherein the bristles are set is caused to expand.

It is also an object of the present invention to provide a novel and useful type of brush handle `structure which can be economically made and which comprises a minimum of parts. It is a further feature that the structure according to the present invention is not readily damaged and accordingly does not usually necessitate repair.

The4 invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application.

In the drawing:

Fig. 1 is a perspective view of a handle structure according to the present invention showing a pair of brushes mounted thereon;

Fig. 2 is substantially a vertical sectional view l of the device illustrated in Fig. 1 taken along the midpoint thereof; and

Fig. 3 is a side view of the device illustrated in Fig. 1.

In the illustrated embodiment of the present invention a handle I 0 is provided with a T- shaped member II carrying a pair of laterally disposed shafts iixedly positioned thereon. It is preferred that the handle III be attached to the member II by forming a tapered threaded surface within the upper portion of said member II substantially as indicated at I2 which, cooperating with a similar formation on the handle I0 provides a firm and secure association between said members. The lateral shafts I3 and Mare preferably formed integrally with the head porparent to those skilled in the art that if desired.

(ol. is-lso) the shafts I3 andI4 can comprise a single shaft held in position in an opening in the portion I5 of the member I I.

Brushes generally designated at I6 and I'I comprising bristles I8 and head structures I9 5 are provided with openings passing laterally through the portions I9, said openings carrying bushings, designated at 20, which are firmly held within the openings and are adapted to receive and freely rotate upon the shafts I3 and I4. 10 Washers 2| are provided at the ends of these bushings against which abut the springs 22 and 23, the former also abutting against the shoulder portion'of the head I5 and the latter abutting against another washer 24 which is in turn held 15 Vin place by the threaded head 25 engaging with Y a threaded portion of the shafts I3 and I4. It will be apparent that the tension in the springs 22 and 23 can be adjusted by rotation of the heads 25, openings 26 being formed in said heads 20 whereby they can be substantially advanced along the threaded portions of the shafts.v In use, the tension in the springs is adjusted as aforesaid to suit the requirements lofthe operator. It will be noted thatftheA springs can be 25 rotated independently of ',eacl'i` omen-whereby they can be positioned as shown in Fig. l or other'. positions, 'for example that illustrated in Fig. 3, in which they are shown disposed substantially perpendicular relative to each other.

It is also notable that, if desired, the heads can be advanced along the threaded portion of the shafts as hereinbefore mentioned, whereby,v the tension in the springs 22 and 23 is increased toan4 extent such that further compression of 35 the springs is substantially precluded, thereby causing the brushes to be held on the shafts in` a manner whereby rotation thereon is at least largely prevented. In this manner, it will be apparent that if desired the brushes can be held 40 yieldably rotatable on the handle or can be' mounted in substantially fixed position.

Further, it is notable that when the device according tothe present invention is used in scrubbing or painting a flat surface, for example 45 a floor,` that the spring tension tends to increase the pressure with whichthe brushes bear upon the floor by increasing the tension which the operator must use in order to keep the brushes substantlally level with the floor. In other words, 5o when the spring;A tension is at its maximum the brushes will be inclined to move in unison with the movement of the operating handle and to maintain the brushes substantially level with the floor while altering the angularity of the handle so f it"will be necessary to increase the tension which l is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims. y

What I claim is:

1. In..a brush structure of the type described, an operating handle, a T-shaped member, means for associating said T-shaped member in said operating handle, laterally extending shafts carried on said T-shaped member, slidable springpressed members carried on said shafts, springs on each end of each shaft, brushes comprising block portions and bristle portions, said block portions hav-ing openings formed therein and extending therethrough adapted to receive said laterally extending shafts, said springs being disposed in countersunk portions formed in .each side wall of said block, said. brushesbeing adapted to be rotatably carried on said shafts positioned between said springs whereby said brushes are yieldably held in position during rotation on said shaft.

2. In a brush structure of the type described, an operating handle, a T-shaped member, a threaded opening formed in one of said arms adapted to engage and cooperate with portions of said handle whereby said member can be firmly but removably carried on said handle, laterally extending shafts carried by said T-shaped member, slidable spring-pressed members carried on said shafts, springs on each end of each shaft, brushes vcomprising block portions and bristle portions, said block portions having openings formed therein and extending therethrough, bushings positioned within said openings frictionally engaging with the walls thereof, said bushings being adapted to freely receive said shafts, said brushes being adapted to be rotatably carried on said shafts positioned between said springs whereby said brushes are independently rotatable and are yieldably held in position during rotation on said shafts.
